There is one important note concerning the implementation of Baah et al.'s original technique based on linear regression [1]}. With that technique, the only covariate in the regression model was a coverage indicator for the forward control dependence predecessor of the target statement. For this study, we have modified Baah et al.'s technique by including the variables used at the target statement as covariates. We believe this is a notable improvement on the original technique. The modified version almost always performs second best among the studied methods.
